CraAuthentication(String secret): Initializes the authentication method with the secret aka password

hashCode → int: The hash code for this object.
no setterinherited
onChallenge → Stream<Extra>: When the challenge starts the stream will provide the current Extra in case the client needs some additional information to challenge the server.
no setteroverride
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
secret ↔ String: getter/setter pair

challenge(Extra extra) → Future<Authenticate>: This method is called by the session if the router returns the challenge or the challenges extra respectively. This method proceeds the cra authentication process and creates an authentication message according to the wamp specification
override
getName() → String: This method is called by the session to identify the authentication name.

hello(String? realm, Details details) → Future<void>: This method is called by the session to modify the hello details for a given realm. Since CRA does not need to modify it. This method returns a completed future
override
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.

toString() → String: A string representation of this object.

deriveKey(String secret, List<int> salt, {int iterations = defaultIterations, int keylen = defaultKeyLength, dynamic hmacLength = 64}) → Uint8List: Creates an derived key from a secret, salt, iterations, keylen and hmacLength.
encodeByteHmac(Uint8List key, int keylen, List<int> challenge, {dynamic hmacLength = 64}) → Uint8List: Creates a hmac from a key that usually is the derived key, keylen, challenge and hmacLength.
encodeHmac(Uint8List key, int keylen, List<int> challenge, {dynamic hmacLength = 64}) → String: Creates an base 64 encoded hmac from a key that usually is the derived key, keylen, challenge and hmacLength.
